Unusual Fire & Explosion Hazards:
Treat as a hydrocarbon type fire. Hot asphalt may ignite flammable materials on contact. DO NOT direct water into a container or
directly onto hot asphalt, a vessel or a storage tank containing hot asphalt as it may cause violent eruptions and spreading of hot
asphalt.
Fire-Fighting Instructions:
Use self-contained breathing apparatus (SCBA) and full bunker turnout gear in a sustained fire. Wear protective clothing
ensemble as defined in NFPA 1500 (1997, or as updated).
Hazardous Combustion Products:
Primary combustion products are carbon monoxide, carbon dioxide and water. Combustion products may include sulfur oxides
and hydrogen sulfide. Other undetermined compounds could be released in small quantities.
* * * Section 6 - Accidental Release Measures * * *
Containment Procedures:
Contain spills with an inert absorbent material such as soil, sand or oil dry.
This material will settle out of the air. It can then be scooped up or vacuumed for disposal as a non-hazardous waste. This
material will sink and disperse along the bottom of waterways and ponds. It cannot easily be removed after it is waterborne;
however, the material is non-hazardous in water.
Clean-Up Procedures:
Solidify with inert absorbent material such as sand or oil dry, pick up and put into suitable container for disposal.
Check with local authorities for approval to dispose of this material.
Response Procedures:
Isolate area. Keep unnecessary personnel away.
Special Procedures:
None.
* * * Section 7 - Handling and Storage * * *
Handling Procedures:
Do not get this material in your eyes or on your skin and minimize exposure to fumes. Wash exposed areas thoroughly after
handling this product. Keep this product from sparks or open flame. Use this product with adequate ventilation. Avoid heating
asphalt within 25ºF of actual flashpoint
Hydrogen sulfide may be emitted from heated asphalt and may accumulate in storage tanks and bulk transport containers.
Prolonged breathing (greater than 1 hour) of concentrations of hydrogen sulfide around 50 ppm can produce eye and respiratory
tract (mouth, nose, and throat) irritation, and at high concentrations (around 300 ppm) is considered immediately dangerous to life
and health.
Since the sense of smell becomes rapidly insensitive to hydrogen sulfide, its odor cannot be relied upon as an indicator of its
concentration. Always use caution when working around closed bulk containers of asphalt. Use ventilation or work upwind from
source of fumes or vapors. Use supplied air respirators or self-contained breathing apparatus if the PEL or TLV for hydrogen
sulfide (10 ppm, 8hr TWA) is exceeded.
See Appendix for suggestions regarding how to avoid building odor complaints for hot applied roofing applications
Storage Procedures:
Store hot product in a well-ventilated area.

Carcinogenicity:
A: General Product Information
Roofing Asphalt: In March, 1987, the International Agency for Research on Cancer (IARC) classified bitumens (such as petroleum
asphalt in this product) as a Group 3 material, "not classifiable as to its carcinogenicity to humans." This classification was made
based on inadequate evidence for the carcinogenicity of undiluted airrefined bitumens in experimental animals and inadequate
evidence that bitumens alone are carcinogenic to humans. However, asphalt does contain a trace amount of polycyclic aromatic
hydrocarbons. Some polycyclic aromatic hydrocarbons have been shown to cause cancer and respiratory damage.
Based on a 2000 review of health effects literature, NIOSH concluded that roofing asphalt fumes are a potential occupational
carcinogen.

APPENDIX
How to Avoid Building Odor Complaints
Hot Applied Roofing Applications
• Effective communication with building occupants before & during project.
• Control kettle temperature to reduce risk of kettle fires and fume emissions. Operate kettles at the lowest possible temperature
that allows proper application. Avoid heating asphalt within 25ºF of actual flash point.
• Kettles should have tight fitting lids and be used in well-ventilated areas.
• Locate kettle down wind from building air intakes, doors or other openings
• Pre-plan the job with contractors, building owners/operators & facility maintenance or engineering.
• Evaluate need for controls to reduce potential for fumes to enter air intakes or building entryways, such as:
• Use portable fans or other engineering controls to direct fumes away from operating air intakes or building openings
• Ventilation System Modifications
• Consider blocking air or sealing off intakes when feasible.
• Alter the building ventilation system to create positive pressure
• Consider shut down of some or all air handlers for critical times
• Use of alternate work schedules (after hours or during minimized occupancy times) to mop near air intakes or building
openings
